脈沖除塵器的結構主要分為動力（風機）單元，脈沖反吹單元，濾筒過濾單元，粉塵收集單元和電控單元，對于防爆除塵器需要增加泄爆和隔爆裝置。下面虹森機電帶你了解中央集塵系統負壓除塵器的結構特點。

The structure of pulse dust collectors is mainly divided into power (fan) unit, pulse backwash unit, filter cartridge filtration unit, dust collection unit, and electrical control unit. For explosion-proof dust collectors, explosion-proof and explosion-proof devices need to be added. Below, Hongsen Electromechanical will take you to understand the structural characteristics of the negative pressure dust collector in the central dust collection system.

風機單元：采用電機和風葉直連式設計，噪音低，傳動效率高。風葉采用鋁合金材質，并經過動平衡測試，電機采用西門子電機，防護等級IP55，滿足現場24小時使用的要求。

Fan unit: adopts a direct connection design of motor and fan blades, with low noise and high transmission efficiency. The fan blades are made of aluminum alloy material and have undergone dynamic balance testing. The motor is a Siemens motor with a protection level of IP55, which meets the requirement of 24-hour use on site.

脈沖反吹單元：采用螺旋式噴吹設計，連接氣源即可使用，可以對濾芯進行360度噴吹，清灰無死角，保證濾芯可以處于較高的過濾風速，延長濾芯使用壽命。脈沖閥雙膜片噴吹，噴吹壽命達到100萬次以上。

Pulse Blowback Unit: Adopting a spiral spray design, it can be used by connecting the air source. It can spray the filter element 360 degrees to clean the dust without dead corners, ensuring that the filter element can be at a high filtering wind speed and extending its service life. Pulse valve dual diaphragm spraying, with a spraying life of over 1 million times.

濾筒過濾單元：標配日本東麗聚酯纖維濾材，PTFE覆膜處理后對0.3微米以上粉塵的過濾效率達到99%以上，濾芯表面光滑，透氣性好，過濾面積大。濾芯立式安裝，避免濾芯表面粉塵堆積。

Filter cartridge filtration unit: equipped with Japanese Dongli polyester fiber filter material as standard, the PTFE film coating treatment can achieve a filtration efficiency of over 99% for dust above 0.3 microns. The filter element has a smooth surface, good breathability, and a large filtration area. The filter element is installed vertically to avoid dust accumulation on the surface of the filter element.

粉塵收集單元：采用抽屜式粉塵收集結構，只需打開門板即可快速對粉塵進行傾倒，可設計不停機卸料和料位報警功能。

Dust collection unit: adopts a drawer type dust collection structure, which can quickly dump dust by opening the door panel. It can be designed with non-stop unloading and material level alarm functions.

電控單元：主要電器件采用施耐德品牌，具有缺相，過載，過熱，相序保護等功能，電控面板操作簡單。

Electronic control unit: The main electrical components are made of Schneider brand, with functions such as phase loss, overload, overheating, and phase sequence protection. The operation of the electronic control panel is simple.

防爆設計：除塵器安裝泄壓膜片，當除塵器內部壓力達到設定值后，可以自動開啟，快速對除塵器內部進行泄壓，避免發生更大的破壞。按照相關規范要求，中央集塵系統防爆措施必須采用兩種或以上的方式。

Explosion proof design: The dust collector is equipped with a pressure relief film. When the internal pressure of the dust collector reaches the set value, it can automatically open to quickly relieve pressure inside the dust collector, avoiding greater damage. According to relevant regulations, the explosion-proof measures for the central dust collection system must adopt two or more methods.
